Windows computers or laptops are sometimes attacked by viruses or malware, but any slowness or unusual behavior in the system is not a sign of a virus. So how do we know if our system is infected? Stay with us to get to know the methods of detecting computer viruses and scanning them completely.
What is Malware?
We have two types of programs, one is malware and the other is malware. I was joking, don’t take it seriously. Any software whose main purpose is to destroy the system is called Malware, which stands for Malicious Software, and a computer virus is one of the types of malware. Malware is divided into three general categories.
- Malware that reproduces, such as viruses and worms
- Malware that aims to hide, such as Trojans and logic bombs
- Malware designed for financial gains, such as spyware or ransomware
What is a computer virus?
A virus is a malicious malware that is specially designed to infect your operating system, and the main purpose of a virus is to reproduce, but this reproduction does not happen automatically, and it is definitely necessary for the user or human to perform an action that causes it to reproduce. This propagation of the virus is done inside programs and software, and its purpose is to destroy your software, operating system, and information. Just like the corona virus, which is very interested in multiplying, but an action must be done by us in order for it to be transmitted, for example, rubbing an infected hand on the eye.
How do we get a computer virus?
The most important method of virus transmission and infection is through downloading email attachments. Other methods of transfer include downloading or opening an application on social networks, via CD/DVD, external hard drive or part of a software that appears to be a useful application. A virus attaches itself to a software in various ways to avoid being detected. The virus is not transmitted over the network and it is not controlled remotely, but if we have a shared folder that everyone uses, it becomes possible to transmit the virus because different people have access to it and it is possible for them to run the virus or enter it. Make your own computer.
As we said before, the virus is not transmitted by itself, and an action must be taken by humans to transmit the virus. But as soon as the virus infects a system, it starts replicating within that system but cannot damage another system by default. For example, we unintentionally copy the virus into a flash drive and give it to others, and thus the virus spreads
How to prevent virus infection?
Apply updates
Many types of viruses work by exploiting security flaws in your programs or operating system. To fix these known security vulnerabilities and protect their users, programmers and software developers regularly release updates that should be applied to your device as soon as they become available.
Although it may be annoying to see update notifications in pop-ups and ignore them, keeping your software up-to-date is critical to keeping your device secure and reducing the risk of malware infection.
Install a good antivirus
There are good options for antivirus and antimalware software on the market, so take the time to think about your needs. Read some reviews and install a few different trial versions (not at the same time) to get a feel for each product for your convenience.
Avoid copied software
Copying software poses a significant security risk (not to mention the serious ethical implications), and while there are few statistics, it is not uncommon for copied software to be infected with malware such as password-stealing Trojans, ransomware, and cryptojacking.
There are many free and open source commercial apps and productivity tools that provide similar functionality to paid app alternatives, while gamers can legitimately enjoy an array of top-notch games without paying a dime because the developers They are increasingly embracing free-to-play models.
Remove programs you don’t need
Over the years, you’ve probably accumulated a bunch of apps on your PC and mobile devices that you never use. It’s time to get rid of them. Unpatched and misconfigured software are common entry points for malware. Therefore, removing unnecessary programs can reduce the risk of getting a virus as well as free up storage space.
If you have already installed unnecessary programs, select them from the list of programs installed in your memory and then delete them completely. Keep only the software you really need. During the installation, carefully read the instructions that appear in the installation steps dialog box to make sure that you do not accidentally install any unwanted programs. Do not run any suspicious or known file by antivirus
How to detect a computer virus
Poor performance, programs not working properly, and computer hangs can sometimes be a sign of a virus or other malware in the system. But these are not always a sign of viruses and malware, but many other problems can lead to a slow computer.
Note that just because your system is working properly does not mean that no virus or malware is threatening it. Viruses have been using system resources in a terrible way for the last decade, and new malware likes to stay in the background of your system undetected so that they can steal your credit card numbers or other personal information. record In other words, today’s modern malware are often created by criminals to make money and generally do not cause any noticeable problems on the computer.
Of course, slowness and weakness in running computer programs may be one of the signs of malware. Note that strange functions on the system may be a sign of the presence of a virus, but once again we point out that they are not the reason for the presence of malware in the system. There is no way other than scanning the computer for malware. Sometimes malware causes problems in the system and sometimes it behaves completely normally in the system, while they secretly achieve their goals in your system. So, the only way to detect a computer virus and the presence of malware is to scan and test the system for their presence.
How to know if the system is virus or not?
To find out if a process in Windows is a virus or not, it is enough to refer to the Task Manager section. To access this section, you can press Ctrl + Shift + Esc keys simultaneously on your keyboard.
When the Task Manager window opens, you will be able to see a list of processes running in Windows. To view the complete list, you must click on the More Details option. Note that some processes have strange and confusing names, this is normal. These processes exist in the background of Windows because the manufacturer or the programs you installed often added them.
Malwares often use a lot of CPU, memory or disk resources and you may see them in this section. To make sure if it is a malware program or not, just right-click on it in Task Manager and click Search online for more information.
If information about malware appears during the search, this is a sign of their possible existence. However, don’t think that if a process looks normal to you, the system is free of viruses. If you are concerned about the possible presence of malware, we recommend running an anti-malware scan.
tip:
Note that “Search Online” option is not available in Windows 7. If you are using Windows 7, you should search for the name of the suspicious process in Google or another search engine.
How to scan your computer or laptop?
Now that you are familiar with the methods of detecting a computer virus, you need to scan it so that you can detecting computer viruses or malware. Windows 10 can scan the computer by default due to the Windows Defender program. Of course, it should be mentioned that you can also scan the Windows computer manually. To access this section, in Windows 10, open the Start menu and type Security. Now click on Open Windows Security to open it. You can also do this in another way. First, click on Settings and select Update & Security. Now select Windows Security and click on Open Windows Security.
Now, to perform an anti-malware scan, click on the “Virus & threat protection” option.
Now click on the “Quick Scan” option to scan the system for malware. Windows Security will now perform the scan and show you the results. If any malware is found, you will be prompted to remove it from your system automatically.
If you are always worried about the possibility of malware and you think that your basic antivirus is not working properly, you can use other security programs.
We recommend using Malwarebytes because it is very compatible with Windows Security. The free version of this program allows you to manually scan the system and the paid version provides better protection. If you just want to test your computer, you can use the same free version which works great.
Note 1:
Windows 7 is not equipped with an internal antivirus like Windows 10. Rather, you have to download and install an antivirus for it. If you are using Windows 7, you can download Microsoft Security Essentials for free and to detect computer viruses. This security program has the same structure as Windows Security in Windows 10.
Note 2:
If your antivirus detects malware but has trouble removing it, try scanning in Safe Mode to fix the problem. You can also ensure that you do not have malware on your system by resetting Windows 10 to its default state.
